STOP FOR BITCHES.

Patented Nov. 11, 1913.

Application filed December 16, 1912. Serial No. 737,046.

To all whom it m ag concern 7 Be it known that I, H. PATRICK, a citizen of the United States, residing at Pony, in the colnity of llladisen, State of Montana, have invented certain new and useful Improvements in- Stops for Ditches; and I do hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to. improvements in water stops for ditches such as are employed for purposes of irrigation.

The principal object of this invention is to provide a stop which is capable of being readily projected into the bed of a ditch and thence spread laterally across the ditch.

Another object of the invention is to provide a stop of the character described which includes a pair of plates, a flexible web eonstituting a wall connecting the plates, and a novel means for spreading the plates and consequently stretching the web.

A further object of the invention is to provide a stop of the character described which is composed of a minimum number of parts, is therefore simple in construction, and is cheap to manufacture.

With these and other objects in view, the invention consists in certain novel features of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure 1 is a perspective view showing the application of the invention, Fig. 2 is a detail top plan view thereof, Fig. 3 is a'face view of the stop showing the parts in their collapsed relation, Fig. 4 is a rear view of the stop showing the parts in their extended relation, and Fig. 5 is a detail sectional view showing the means employed for connecting the web to the plates.

Like reference numerals designate corresponding parts in all the figures of the drawing.

Referring to the drawing, my invention comprises a pair of plates 55 which are I disposed side by side and in the same plane,

the outer edges 66 being inwardly curved to the bottom of the inner edges 7? to form a central point at the lower end of said plates.

Apair of crossed hand levers 8.8 are piv otally connected adjacent their lower ends, as at 9, and the extreme lower ends of said levers are fulcrumed, as at l l0, to the lower inner portions of the plates" 5. Forwardly projecting from the upper inner portions of said plates 5 are pins 1l.ll which respectively project through longitudinal slots 1212 formed in said levers.

Keepers 1313 each have one end connected,

to arespective plate and the other end to a respective pin to prevent accidental dis Pla em t f t e l v r- These l v Proje t abpve the plates 5 to form handles 14 "14.

to permit of the plates being extended for a certain distance. The lower portion of this web extends below the plates, as indicated by the reference numeral 1.8.

In practice, the plates 5 are first disposed in their collapsed position and the point is then forced into the bed of the ditch. The hand levers are then forced outwardly, and as a result of the pivot 9 being disposed adjacent the lower ends, the upper portions of the plates will be forced farther apart than the lower portions. The outer edges (3 of these plates are forced into the sides of the ditch and the lower portion 18 of the web is folded rearwardly upon the bottom of the ditch. Dirt is then placed upon the projecting portion of the web for holding the same against the influence of the water.

The plates 5 have pivoted thereto the outer ends of locking arms 19 and 21 respectively and the free ends of these arms are provided with openings which are adapted to be brought into registration for the insertion of a locking pin 21. Slidable onthe arms 19 and 21 is a sleeve 20 which in conjunction with the locking pin 21 serves to secure the arms 19 and 21 against relative movement and thereby lock the upper ends of the plates 5 in spread position.

Vhat is claimed is 1. In a water stop for ditches, a pair of plates having their outer edges inwardly curved to the bottom of the inner edges to form a resultant central point at the bottom of said plates, a flexible web connecting the plates, and means for spreading said plates. I 2. In awater stop for ditches, a pair of plates, a flexible Wall having downwardly converging side edges'secured at said edges to the inner sides of the respective plates, and means connected to the plates for spreading the same and stretching the web.

3. In a water stop for ditches, a pair of plates, a flexible web connecting the plates, and a pair of crossed hand levers pivo-tally connected adjacent their lower ends and having their extreme lower ends fulcrumed to the inner portions of the respective plates, the upper portions of the levers beyond their pivotal connection having pin and slot connections with the upper portions of therespective plates, whereby upon outward movement of the levers the upper portions of the plates will be spread farther than the lower portions.

4. In a water stop for ditches, a pair of plates having their outer edges inwardly curved to the bottom of the inner edges to form a resultant central point atthe bottom of said plates, a flexible web connecting the plates, and means for spreading said plates.

5. In a water stop for ditches, a pair of plates having their outer edges inwardly curved to the bottom of the inner edges to form a resultant central point at the bottom of said plates, a flexible web having. downwardly converging side edges secured at said edges to the inner sides of the respective plates.

In testimony whereof, I afiiX my signature, in presence of two witnesses.
